Erythrodermic psoriasis

What is erythroderma?

Erythroderma is a generalised redness of the skin. It is a very severe skin condition that can be fatal. It can be the result of many inflammatory skin conditions, drugs and malignancies but in a third of cases it is due to psoriasis.

What are the clinical features of erythrodermic psoriasis?

Erythrodermic psoriasis usually occurs in the setting of known worsening or unstable psoriasis but may uncommonly be the first presentation of psoriasis. Onset can occur acutely over a few days or weeks, or gradually evolve over several months from pre-existing psoriasis.

Features are those of any form of erythroderma (red dry skin all over the body).
